The invention discloses a length-adjustable variable cross-section frame and a vehicle and relates to the technical field of vehicle structures. The length-adjustable variable cross-section frame comprises two longitudinal beams which are arranged at an interval and connected, and each longitudinal beam comprises a first longitudinal beam part and a second longitudinal beam part, the second longitudinal beam part is connected with the first longitudinal beam part, the connecting length of the second longitudinal beam part and the first longitudinal beam part is adjustable, and a lower wing surface of the second longitudinal beam part is higher than a lower wing surface of the first longitudinal beam part. According to the length-adjustable variable cross-section frame, the length of the frame can be increased, the available space in the length direction is further enlarged, the volume of a trailer is increased, in addition, when the variable cross-section is adopted for the frame, and the rear axle housing is connected with the lower wing face of the second longitudinal beam part, the overall height of the frame is reduced, the available space in the height direction is further enlarged, and the volume of the trailer is increased. The length-adjustable variable-section frame is advantaged in that, on one hand, the length of the frame can be increased, on the other hand, the height of the frame can be increased, and the volume of the trailer is greatly increased.

    本发明公开了一种可调节长度变截面车架及车辆,涉及车辆结构技术领域,包括:两个间隔设置且连接的纵梁,每个所述纵梁均包括:第一纵梁部和第二纵梁部,所述第二纵梁部与所述第一纵梁部连接且所述第二纵梁部与所述第一纵梁部的连接长度可调节,所述第二纵梁部的下翼面高于所述第一纵梁部的下翼面。本发明的可调节长度变截面车架,可以增加车架长度,长度方向可利用空间进一步加大,提升挂车容积,另外车架采用变截面,后桥桥壳与所述第二纵梁部的下翼面连接时,车架整体高度降低,高度方向可利用空间进一步加大,提升挂车容积。因此,本发明的可调节长度变截面车架,一方面可增加车架长度,另一方面可增加车架高度,大幅提升挂车容积。
